Whenever a nontoken creature you control enters, you may scry 1. (To scry 1, look at the top card of your library. You may put that card on the bottom of your library.)

Exile the bottom card of your library, a card from your hand, and a card you own from outside the game. Put them in a face down pile, shuffle that pile, then manifest those cards. (To manifest a card, put it onto the battlefield face down as a 2/2 creature. Turn it face up any time for its mana cost if it's a creature card.)

{T}, Sacrifice Worldshaper Adept: Choose two basic land types. Create a tapped colorless land token of the chosen types.

Whenever equipped creature deals combat damage to a player, destroy all permanents other than Worldslayer.
Equip {5}

Vigilance
Whenever a creature you control survives damage, it explores. (Reveal the top card of your library. Put it into your hand if it's a land. Otherwise, put a +1/+1 counter on this creature, then you may put that card in your graveyard.)

Whenever equipped creature attacks, it gets +2/+2 and gains trample until end of turn.
Equip {2}

Each opponent sacrifices an artifact.
Scry 1.
Coalesce {6}{R} (You may cast this from your graveyard for {6}{R}. If you do, it enters as a Horror creature after it resolves. Exile it if it would leave the battlefield or not resolve.)

Experience (Whenever this creature attacks, if it has fewer than three +1/+1 counters on it, put a +1/+1 counter on it.)
When Worried Vulpine has three or more +1/+1 counters on it, remove them all and transform it.

Vanishing 4 (This permanent enters with four time counters on it. At the beginning of your upkeep, remove a time counter from it. When the last is removed, sacrifice it.)
Whenever a time counter is removed from Worship in Vain, discard your hand, then draw a card for each time counter on Worship in Vain.

Ferocious — At the beginning of each combat, if you control a creature with power 4 or greater, Worshipper Whelp gets +2/+0 until end of turn.

Destroy target land. Then, judge target creature you control. (Honor it by putting a +1/+1 counter on it or condemn it by sacrificing it to draw a card.)

When this permanent transforms into Worthy Vulpine or at the beginning of combat on your turn, creatures you control gain haste and trample until end of turn.

{T}: Add {C}.
{T}: Add one mana of any color. Spend this mana only to cast Aura or Aurashaper spells.

Choose target creature you control. If it has a +1/+1 counter on it, put an additional +1/+1 counter on it. Then it fights target creature you don't control.

Legacy (You may play this side of this card only from your graveyard. Exile it if it would be put into a graveyard or not resolve.)
For each of up to two target creatures you control, put a +1/+1 counter on it, then you may have it deal damage equal to its power to any target.

Haste
When Wretched Merfolk enters, target creature can't block this turn.

Trample
Whenever Wun Su, Guru of the Staff deals combat to a player, you may create Wun Su's Staff, a legendary colorless Equipment artifact token with “Equipped creature gets +5/+5” and equip {5}, then attach it to Wun Su.

As an additional cost to cast this spell, sacrifice a land.
Create a 6/6 red Wurm creature token with “This creature can't be blocked by creatures with flying.”

Landfall — Whenever a land you control enters, create a 5/5 green Wurm creature token with trample.

Wyrmfire deals 3 damage to target creature or planeswalker. Excess damage is dealt to that permanent's controller instead.

Whenever an enchantment you control enters, draw a card.

Choose one —
• Copy target instant, sorcery, or Equipment spell you control. You may choose new targets for the copy.
• Create a token that's a copy of target Equipment you control.

Whenever you cast an instant or sorcery spell, you may have Xenocrata's Fleet become a 4/4 Ship artifact creature with haste until end of turn.
Whenever Xenocrata's Fleet deals combat damage to an opponent, create that many 1/1 red Warrior creature tokens.

Trample, vigilance
Spells your opponents cast that target Xiejuan and Hao Lu cost {X} more to cast, where X is the number of other creatures you control.
Whenever another creature you control dies, draw a card.

Alpha (You may have this creature enter with a +1/+1 counter on it. If you do, it becomes alpha and can only attack alone.)
When Xiejuan, the Regal Beast becomes alpha, draw a card for each other creature you control.
